180602 divided by 71 
The aim is to understand the frequency of 71 in 180602.

Step 1:
1 divided by 71 is 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Grab the next digit (8) from the dividend, add it to 1, then carry on: 18 / 71

Advancing to step 2:
The number 71 fits into 18 0 times, leaving a remainder of 18.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 18, we end up with 18.
Include the next digit (0) from the dividend after 18, then repeat: 180 / 71

Moving on to step 3:
71 can be fit into 180 2 times, resulting in a remainder of 38.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we subtract 142 from 180, we get 38.
Include the next digit (6) from the dividend after 38, then repeat: 386 / 71

Step 4:
71 goes into 386 5 times with a remainder of 31.
The next digit of our result is 5. 
Result so far: 25.0
If we take 355 away from 386, we end up with 31.
Append the next digit (0) from the dividend to 31 and continue with: 310 / 71

Going ahead to step 5:
If we divide 310 by 71, we get 4 and a remainder of 26.
Write down 4 as next digit of the result. 
Result so far: 254.0
Subtract 284 from 310 to get 26.
Include the next digit (2) from the dividend after 26, then repeat: 262 / 71

Step 6:
When dividing 262 by 71, we get 3 with a remainder of 49.
The number 3 becomes the next digit in our result. 
Result so far: 2543.0
The remainder is 49 after subtracting 213 from 262.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Step 7:
71 goes into 490 6 times with a remainder of 64.
Write down 6 as next digit of the result. 
Result so far: 2543.6
The remainder is 64 after subtracting 426 from 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Advancing to step 8:
71 goes into 640 9 times with a remainder of 1.
Record the quotient 9 as the next digit in the result. 
Result so far: 2543.69
If we take 639 away from 640, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 9:
When dividing 10 by 71, we get 0 with a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 2543.69
Subtract 0 from 10 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 10:
100 divided by 71 is 1 with a remainder of 29.
The number 1 becomes the next digit in our result. 
Result so far: 2543.6901
Subtracting 71 from 100 leaves us with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Going ahead to step 11:
The number 71 fits into 290 4 times, leaving a remainder of 6.
The number 4 becomes the next digit in our result. 
Result so far: 2543.69014
If we take 284 away from 290, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 12:
When dividing 60 by 71, we get 0 with a remainder of 60.
Use 0 as the next digit of our solution. 
Result so far: 2543.69014
Subtracting 0 from 60 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 13:
71 goes into 600 8 times with a remainder of 32.
Use 8 as the next digit of our solution. 
Result so far: 2543.6901408
If we take 568 away from 600, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Step 14:
When dividing 320 by 71, we get 4 with a remainder of 36.
Use 4 as the next digit of our solution. 
Result so far: 2543.69014084
Deduct 284 from 320 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

The final outcome is 2543.69014084, with a leftover of 3.6e-08.
